Is a NAT on PPTP interface a taboo subject ?

Is a NAT on PPTP interface a taboo subject ?
It is strange that i m the only people who gets the problem.

If your LAN is on 192.168.0.0/24 and if the LAN of the PPTP client is also on 
192.168.0.0/24 (and this case if not rare) how can pptp client send packet to 
the remote LAN ?
The workstation will sent all packets to his LAN interface and not to VPN :(

Cya and thanks for any help.

Sorry for this reply from myself :)

                Objet : NAT on PPTP interface

                Hello all.

                I just want to use NAT on the PPTP interface of Monowall.

                Here is my network:



                                        VPN client (local adress 192.168.0.1/24 
, vpn adress 192.168.1.192/28)

                I want to enable NAT between VPN client and routeur 192.168.0.2
                But on the NAT configuration of Monowall i can't select "PPTP" 
as external adress.
                Must i add "192.168.1.1" as "server NAT" on the server NAT page 
?
                Can i not use a symbolic name like "PPTP interface" ?
                It is the case for "wan interface".

                Sorry for my english, it is not my primary language.

                Thanks u in advance.
